Abstract
A method for operating a magnetic field sensor and an associated magnetic field sensor system. The method includes: detecting an output signal of the magnetic field sensor that describes a magnetic field detected by the magnetic field sensor; establishing an adaptive filter function of an adaptive filter based on a model that describes an influence of specific objects on the output signal; filtering the output signal with the aid of the adaptive filter; ascertaining a deviation between the output signal and the output signal filtered with the aid of the adaptive filter; and detecting a presence of an object to be detected, based on the ascertained deviation.
